CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 339,913, dated April13,1886.

Application filed August 31, 1883. Serial No. 105,182. (No model.)

T0 at whom it may concern.-

Be it known that I, HARRY O. MoOAR'rY, a citizen of the United States,residing in Williamsport, county of Lycoming, State of Pennsylvania,have invented a new and useful Improvement in Oar-Trucks, whichimprovement is fully set forth in the following specificationand-accoinpanying drawings, in which Figure 1 is a side elevation of acar-truck embodying my invention. Fig. 2 is a side elevation of theupper and lower bolster thereof embodying my invention. Fig. 3 is a topor plan view of the upper bolster. Fig. 4 shows a side elevation of atruss rod seat.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of the construction of a metallic bolster ofcar-trucks, as will be hereinafter fully set forth.

In the drawings, A represents the side irons of a car-truck, and B thesupporting-c0lumns thereof.

0 represents the upperbolster of the truck, the same being sustained onthe springs D; and E represents the lower bolster thereof, which restson the side irons and sustains said springs D.

The upper bolster is formed of the top iron bar, F, and lower iron bar,G, the bar F being arched and bolted at its ends to the bar G, andbetween the bars are the supporting metallic columns H, which rest onthe bar G, and on which the crown orv central portion of the bar Frests, said bars and columns being firmly bolted together.

J represents the side bearings, which rest on and are bolted to the barF, and have connected with them the ends of the truss-rods K, which areof inverted-arch form.

Bolted or otherwise secured to the bar G are truss-rod seats L, whichdepend from said bar and form the seats for the arch portions of thetruss-rods K.

Interposed between the bars F G, beneath the bearings J, are shortcolumns M, which sustain the contiguous portions of said bars, and aresecured thereto by bolts N, which pass through the bar G, the columns M,bar

F, and bearings J, thus firmly connecting said parts.

On the under side of the ends of the bar G are secured the plates 1?,whose sides are notched or grooved, as at a, to receive the columns B ofthe side irons, said plates thus forming the end guides and supports ofthe upper bolster.

The ends of the bar G are turned upwardly, forming flanges Q, againstwhich the ends of the 'bar F abut.

Bolts N are passed through the bars F G and plates P, which, with thebolts N, employed to secure the plates 1? to the bar G below the columnsM, serve to connect the end portions of the bolster in a firm anddurable manner, it being evident that the bolster, as described, is astrong, serviceable, and reliable structure, without possessing greatweight.

The lower bolster, E, is bolted to the side irons, and has its ends bentunder, as at E, Fig. 2, so as to abut against said side irons and crimpsaid ends, which thus possess increased strength and are securely heldin position.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. As an improvement in car-trucks, the hereinbefore-described bolster,composed of bars connected together at their ends, and having theircenters united and held in relative Vertical positions by means of postsand bolts, in combination with the truss-rods, sub stantially as and forthe purpose set forth.

2. The truss-rods K, in combination with the upper bolster-bar, bearingsJ, for said trussrods, which are secured to said bolster,' theinterposed block M, and the truss-rod seats L, which are interposedbetween said bolster and said truss-rods, substantially as and for thepurpose set forth.

3. The lower bar, G, having flanges Q, turned up on its ends, incombination with the arched upper bar, F, having its ends bearingagainst said flanges, the guide-plates P, bolted to the ends of saidbars under the same, the stops or blocks M, inserted between notched 0rgrooved on their sidesat a, to rebars F and G, near their ends, and thepiloeive the columns B'of the side irons, snbstan-- 1o lars H, alsointerposed between said bars, as tially as and for the purpose setforth. stated. i

5 4. The upper bolster composed of the bent MCCARTY bar F, straight barG, and interposed columns Witnesses: M, in combinatiom with the platesP, secured JOHN A; \VIEDERSHEIM, beneath the bars F G at their ends, andW. F. KIROHER.
